POWER TOOL SAFETY

WARNING: To avoid electrical hazards, fire hazards or damage to the heat

gun, use proper circuit protection. The heat gun is wired at the factory for 110–120 V operation. It must be connected to a 110–120 V, 15 A time delayed fuse or circuit breaker. To avoid shock or fire, replace power cord immediately if it is worn, cut or damaged in any way.

!

ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA REQUIREMENTS or ANSI SAFETY STANDARD Z87.1

FLYING DEBRIS can cause permanent eye damage. Prescription

eyeglasses ARE NOT a replacement for proper eye protection.

WARNING: Non-compliant eyewear can cause serious injury if broken

during operation of a power tool.

WARNING: Some dust created by power sanding, sawing, grinding, drilling

and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

Lead from lead-based paints

Crystalline silica from bricks, cement and other masonry products

Arsenic and chromium from chemically-treated lumber Your level of risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area and work with approved safety equipment such as dust masks

that are specially designed to filter out microscopic particles.

!

!

WARNING: Use hearing protection, particularly during extended

periods of operation of the tool or if the operation is noisy. !

POWER TOOL SAFETY

GENERAL SAFETY RULES

WARNING: Read and understand

all instructions. Failure to follow all

instructions listed below may result in electric shock, fire and/or serious personal injury. WORK AREA Keep your work area clean and well lit.

Cluttered benches and dark areas invite accidents. Do not operate power tools in potentially explosive environments,

such as in the presence of flammable liquids, gas or dust. Power tools create sparks which may ignite the dust or fumes. Keep bystanders, children and visitors away while operating the tool.

Distractions can cause you to lose control. ELECTRICAL SAFETY

Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized plug only one way. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not alter the plug in any way. Double insulation eliminates the

need for the three-prong grounded power cord and grounded power supply system. Avoid body contact with grounded surfaces such as pipes, radiators, ranges

and refrigerators. There is increased risk of electric shock if your body is grounded.

Do not expose power tools to rain or wet conditions. Water entering the power

tool will increase the risk of electric shock. Do not abuse the cord. Never use the

cord to carry the tool or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for

outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use the tool while

tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

Dress properly. Do not wear loose

clothing or jewellery.

Contain long hair. Keep your hair,

clothing and gloves away from moving parts. Loose clothing, jewellery or long hair can be caught in moving parts.

Avoid accidental starting. Be sure the

switch is OFF before plugging in.

Carrying tools with your finger on the

switch or plugging in tools that have the

switch ON invites accidents.

!

POWER TOOL SAFETY Remove adjusting keys or wrenches before turning the tool ON. A wrench or

key that is left attached to a rotating part of the tool may result in personal injury. Do not overreach. Keep proper footing

and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. Use safety equipment. Always wear eye

protection. Dust mask, non-skid safety shoes, hard hat, gloves and hearing protection must

be used for appropriate conditions. TOOL USE AND CARE

Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand

or against your body is unstable and may lead to loss of control. Do not force the tool. Use the correct tool

for your application. The correct tool will do the job better and safer at the rate for which it was designed. Do not use the tool if the power switch does not turn it ON or OFF. Any tool that

cannot be controlled with the switch is dangerous and must be repaired. Disconnect the plug from the power source before making any adjustments, changing accessories or storing the tool. Such preventive safety measures

reduce the risk of starting the tool accidentally. Store idle tools out of reach of children

and other untrained persons. Tools are dangerous in the hands of untrained users.

Maintain tools with care. Keep cutting

tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. Check for misalignment or binding of moving parts, breakage of parts and any

other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool may become hazardous when used on another tool. SERVICE

Tool service must be performed only by qualified personnel. Service or

maintenance performed by unqualified personnel could result in risk of injury. When servicing a tool, use only identical replacement parts. Follow

instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES Move the workpiece outdoors wherever possible. If this is not practical, keep the

work area well ventilated. Open all windows. Place an exhaust fan in one window, making sure it is moving the air from inside the work area to the outdoors. Remove all cooking utensils and food from the work area.

Remove all carpets, rugs and furniture from the work area where practical. If

removal is not practical, move furniture to the middle of the room and cover them with a plastic drop cloth. Seal off work areas from the rest of the dwelling by sealing off doorways with drop

cloths. Cover all air ducts.

Place a drop cloth in the work area to

catch paint chips or peelings.

Wear protective clothing to reduce the

amount of exposed skin . Children, pregnant or potentially pregnant women and nursing mothers should not be present in the work area

until the work and cleanup have been completed. Use a respirator mask for dust and fumes which has been approved by “OSHA” or “NIOSH”. These masks and

replaceable filters are available at most major hardware stores. Make sure the mask fits properly. Beards and facial hair may prevent the maks from fitting properly. Change filters often. Disposable paper dust masks are NOT adequate for protecting against inhaling lead fumes. Keep the heat gun moving while heating the paint. Excessive heat will generate

increased amounts of fumes which can be inhaled by the operator.

WARNING – POISON HAZARD: Extreme care must be taken when using

a heat gun to strip paint. The softened paint, residue and vapours of the paint may

contain lead which is poisonous. Any paint used in the construction industry prior to 1977 may contain lead. Once paint is applied to the surface, hand-to-mouth contact can result in the ingestion of lead. Breathing the vapour resulting from the heating process or dust from a sanding process may also result in the ingestion of lead. Exposure to any amount of lead can cause irreversible brain and nervous system damage. Young and unborn children are particularly vulnerable to lead poisoning. Before starting any paint removal process you should determine if the paint you are removing contains lead. Your local health authority or a professional who uses a paint analyzer can determine the level of lead contained in the paint to be removed. Lead- based paint must only be removed by a professional and must not be removed using a heat gun.

SPECIFIC SAFETY RULES WARNING – POISON HAZARD: - cont’d

Keep food and drinks out of the work area. Always wash hands, arms and face

and rinse mouth with water before eating or drinking. Never smoke or chew gum or tobacco in the work area. When the paint stripping operation is completed, clean up all removed paint and dust by wet mopping the floors. Do

NOT sweep or vacuum dusty areas. Use a solution of trisodium phosphate (TSP) in water to wet mop the floors and clean all walls, sills and any other surface where paint dust has settled. Keep the heat gun in constant motion.

Do not stop or dwell in one spot. Use extreme caution if the opposite side of the work surface such as siding is not accessible. The hidden side could

catch fire if it becomes too hot. Some buildings contain flammable material behind the siding, floors, fascia, soffit boards and other such panels. Check these areas before applying heat. Do not use the heat gun if flammable materials are present or if you are unsure of the flammability of the hidden material. Do not use the heat gun near surfaces with cracks or near metal pipes, flashings, etc. Heat may be conducted

behind the work surface and ignite hidden material.

At the end of each work session, place the paint chips and dust in a double plastic bag. Close the bag with a twist tie

and dispose of it in accordance with local regulations. Remove protective clothing and shoes in the work area to avoid transferring dust into other areas of the building.

Wash work clothes separately using a high quality detergent. Wipe shoes off with wet rag and then wash the rag with the work clothes or dispose of it in the bag of dust and debris. The ignition of hidden material may not be readily apparent and can cause property damage and injury. Do not use the heat gun in the presence of flammable liquids or gases.

Do not use the heat gun near combustible materials such as dry grass,

leaves or paper which can catch fire. Do not lay the heat gun on a flammable surface during operation or immediately

after turning it OFF. The nozzle becomes very hot. Always set the heat gun on a flat level surface so the nozzle is directed upward and and away from the supporting surface.

WARNING – EXPLOSION OR FIRE HAZARD: This heat gun produces

extremely high temperatures which can reach up to 650°C (1202°F). Use extreme caution to prevent combustible materials from igniting. Never use the heat gun near volatile liquids such as cleaning solvents, lacquers, gasoline, etc.

!

SPECIFIC SAFETY RULES Never touch the nozzle immediately after use. It will be very hot and can cause

severe burns. Never use the heat gun as a hair dryer.

The extreme heat will burn your scalp and scorch your hair. Always use gloves while operating the heat gun. Tools and scrapings become

very hot. Always treat the heat gun with the same respect as an open flame. It can burn

you and cause a fire if not handled and used with extreme caution. WARNING: Never operate the heat gun if the blower motor does not turn ON. Turn the heat gun OFF immediately.

Operating the heat gun without the blower motor running will burn the element out. WARNING: Keep the extension cord clear of the working area. Position

the cord so it will not get caught on the workpiece, tools or any other obstructions while you are working with the power tool. Make sure any extension cord used with this tool is in good condition. When

using an extension cord, be sure to use one of heavy enough gauge to carry the current the tool will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

The table below shows the correct size to use according to cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord. Be sure your extension cord is properly wired and in good condition. Always

replace a damaged extension cord or have it repaired by a qualified electrician before using it. Protect your extension cord from sharp objects, excessive heat and damp or wet areas. Use a separate electrical circuit for your power tools. This circuit must not be less than 14 gauge wire and should be protected with either a 15 A time delayed fuse or circuit breaker. Before connecting the power tool to the power source, make sure the switch is in the OFF position and the power source is the same as indicated on the nameplate. Running at lower voltage will damage the motor.

ASSEMBLY & OPERATION HEAT GUN APPLICATIONS

The heat gun is a tool that can be used for many different applications. As with any power tool, there are many factors that will affect its effectiveness and safety. It is important to be aware of these factors before you begin to use the tool. The chart below illustrates examples of several heat gun applications and the temperature setting range that should be used for each of those applications.

Application

Temperature setting (°C)

Removing adhesive backed floor coverings

50°–250°

Removing paint 450°–650°

Drying paint or plaster 50°–250°

Heating electrical shrink tube

250°–450°

Heating shrink wrap 250°–450°

Thawing frozen locks 50°–250°

Thawing frozen metal water pipes

450°–650°

Loosening seized bolts & nuts

450°–650°

Molding and bending plastics

250°–450°

Waxing skis & snowboards

50°–250°

Sealing ends of nylon or polypropylene rope

250°–450°

Heating applications are affected by several factors. The density of the material being heated, ambient temperature, wind, distance between the nozzle and the surface being heated and the heating technique will all affect the speed at which the surface will be heated. Recommended temperature range

It is always safer to start heating the surface with the heat gun temperature set to the lowest temperature within the recommended temperature range for the type of application. If more heat is required, increase the temperature as outlined on Pages 13 & 14. Recommended fan speed range

When starting any heating operation, it is recommended that you set the fan speed at the middle setting. If more or less air flow is required, adjust the fan speed as outlined on Pages 13 & 14. During the heating process, it is very important to maintain a consistent distance between the nozzle and the surface being heated. NOTE: The nozzle must be at least 2”

(25 mm) from the surface being heated to permit adequate air flow and to prevent overheating. Always keep the heat gun in motion during the heating process. Inadequate motion will result in overheating and possible damage to the surface or to the heat gun.

13

ASSEMBLY & OPERATION ON/OFF TRIGGER SWITCH

The heat gun has an ON/OFF trigger switch that is used to turn the heat gun ON and OFF. To turn the heat gun ON squeeze the lower part of the ON/OFF switch (1) (Fig. 1). To turn the ON/OFF switch OFF, squeeze the upper part of the ON/OFF switch (2).

NOTE: When the heat gun is first turned

ON, smoke may appear due to the burning of manufacturing oils on the element. The smoke will disappear within five minutes of operation. DIGITAL TEMPERATURE & FAN SPEED CONTROLS

Both the temperature and the speed of the air coming from the heat gun nozzle can be adjusted using the digital controls located in the rear of the heat gun. NOTES:

a. The ON/OFF trigger switch must be turned ON before the temperature control, fan speed control and the digital display will function.

b. The digital control memory function will automatically set the heat gun at the previously set temperature and fan speed when the switch is turned ON.

Setting the fan speed

The fan speed can be set at five different speeds. Higher fan speeds will move more air through the heat gun and will generally deliver more hot air to the surface being heated.

WARNING: Have you read

“POWER TOOL SAFETY”,

“SPECIFIC SAFETY RULES”,

EXTENSION CORD SAFETY” and

“SYMBOLS” on pages 3 through 9 of

this Manual? If not, please do it now

before you operate this heat gun.

Your safety depends on it!

Every time you use the heat gun you

should verify the following:

1. The nozzle is not obstructed

with debris

2. Appropriate safety glasses,

respirator mask and protective

clothing are being worn

3. Area adjacent to the heating

application is clear of all

combustible materials

4. Availability of water or fire

extinguisher in case of a fire.

Failure to adhere to these safety

rules can greatly increase the

chances of injury or property

damage.

ASSEMBLY & OPERATION ASSEMBLE INTERCHANGEABLE SCRAPER BLADES TO THE HANDLE

The scraper handle can be assembled with the isosceles, convex or concave scraper profiles. 1. Remove the outer nut (1) from the

scraper handle (2) (Fig. 4).

2. Place the appropriate scraper profile (3) onto the threaded portion of the scraper handle. NOTE: Match the “D” shape of the

profile to the threaded handle.

3. Thread the outer nut back onto the handle and tighten it with two 12 mm wrenches. NOTE: Do not over tighten the nuts or

you will strip the threads. INSTALL APPROPRIATE DEFLECTOR TO THE HEAT GUN NOZZLE

The heat gun comes with four nozzles that will create an air flow shape best suited for each heating application:

Wide jet – use for heating a wide area at one time

Air wrap – use for limiting the spread of the air stream

Coned reducer – use for concentrating the air flow onto a small area

Curved head shield – use for shielding sensitive areas from the direct heat.

DANGER: Never attempt to

change or attach a deflector to the heat gun immediately after it has been turned ON. The nozzle will be extremely hot. Always wear gloves when changing or attaching a deflector.

Push the selected deflector (1) onto the

small end of the heat gun nozzle (2)

(Fig. 5).

NOTE: The deflector is simply a friction fit

so it must be firmly pressed onto the small

end of the nozzle.

USING SAFETY STAND WHEN HOT

When heat gun is hot, always place it up

side down on its safety stand (1) (Fig. 6).

STRIPPING PAINT FROM DWELLING

The most common application for the heat

gun is in stripping paint from fascia, soffit

and siding of a dwelling (Fig. 7). Although

the heat gun will work extremely well in this

application, it is important to take specific

precautions and prevent potentially serious

mistakes.

ASSEMBLY & OPERATION

STRIPPING PAINT FROM DWELLING –

cont’d

WARNING: Use extreme caution if

the opposite side of the work surface such

as siding is not accessible. The hidden

side could catch fire if it becomes too hot.

Some buildings contain flammable material

behind siding, floors, fascia, soffit boards

and other such panels. Check these areas

before applying heat. Do not use the heat

gun if flammable materials are present or if

you are unsure of the flammability of the

hidden material.

Do NOT use the heat gun on surfaces that

can be damaged by heat, such as vinyl

siding, vinyl coated siding or vinyl window

frames.

Do NOT use the heat gun on any glass

surface such as windows. The rapid

expansion may break the glass or damage

the seal in thermo pane windows.

The heat gun will soften putty in window

frames. Be careful not to gouge the soft

putty with the scraper. The putty will firm

up as it cools.

When removing paint from the fascia, do

not overheat the edge of the shingles. Too

much heat will melt the shingles.

PAINT STRIPPING PROCESS

WARNING: Never touch the heat

gun nozzle during use or soon after use. It

becomes very hot and will cause severe

burns. Wear gloves to protect your hands

from hot paint scrapings.

When turned ON, the heat gun will heat

the paint causing it to soften so it can be

easily scraped off without damaging the

surface. Some paints may soften when

heated even though they show no signs of

blistering. Some paints will blister when

heated, while others may become rubbery.

Some paints will require more heat than

others to soften them sufficiently for easy

removal.

NOTE: Paint that has been absorbed into

the wood will not be removed with the heat

gun.

When working with several layers of paint,

completely heating the surface all the way

to the wood will speed up the scraping

process. This will allow all layers of paint to

be scraped at one time.

Use a soft wire brush to remove paint from

very intricate surfaces. Mineral paints and

finishes such as cement paint and

porcelain do not soften when heated, so

they cannot be removed using a heat gun.

ASSEMBLY & OPERATION ASSEMBLY & OPERATION

MAINTENANCE

PAINT STRIPPING PROCESS – cont’d

For best paint removal results, move the

gun slowly and steadily forward at an

angle to the surface to be stripped. This

allows you to safely scrape behind the hot

air stream and keeps the scraper and

scraped surface cooler. Holding the heat

gun at an angle also preheats the paint as

you scrape.

The chart below explains the four zones

for the paint removal process (Fig. 8).

Zone Description

1 Warm air preheats the paint

2 Hot air softens the paint

1+2 Heat penetrates complete area

3 Paint can be easily scraped off

as soon as it is softened and the

heat gun is moved forward

4 Stripped surface is allowed to

cool

WARNING: When servicing, use only

identical replacement parts. Use of any

other part may create a hazard or cause

product damage.

DO NOT abuse power tools. Abusive

practices can damage the tool as well as

the workpiece.

WARNING: DO NOT attempt to

modify tools or create accessories. Any

such alteration or modification is misuse

and could result in a hazardous condition

leading to possible serious injury. It will

also void the warranty.

CLEANING

Keep air vents clean and unobstructed to

allow maximum airflow through the heat

gun.

DO NOT use solvents when cleaning

plastic parts. Most plastics are susceptible

to damage from various types of

commercial solvents and may be damaged

by their use. Use a clean cloth dampened

with a mild detergent to remove dirt, dust,

oil, grease, etc.

WARNING: Do not at any time

allow brake fluids, gasoline, petroleum-

based products, penetrating oils, etc. to

come in contact with plastic parts. They

contain chemicals that can damage,

weaken or destroy plastic.

LUBRICATION

All of the bearings in this heat gun are

lubricated with a sufficient amount of high-

grade lubricant for the life of the unit under

normal conditions. Therefore, no further

lubrication is required.
